SHOE CONSTRUCTION Filed May 19, 1944 Patented Sept. 11, 1945v SHOE CONSTRUCTION Olaf G. Beestrum, St. Louis County, Mo., assignor to Samuels Shoe Company, St. Louis, Mo., a corporation oi' Missouri 7 Claims.

This invention relates to shoes, and more particularly to a. shoe of the type which can be made by the insertable last method of construction.

One of the objects of the invention is to produce an improved` exible, light and comfortable shoe by simple-operations.

Anotherobject is to so construct a. shoe by the insertable last method that a cushioned member can be embodied therein in such a manner as to provide a cushioned insole for the shoe.

A further object is to so construct a shoe having a lined upper that the lining can serve as the connecting means between the sock lining, secured to the insole, and the upper and an integral extending part of the lower marginal portion of the outer part of the upper can be employed to encase the insole.

Another'object is to produce a shoe lasted by an insertable last, using an improved method of manufacture.

Other objects ofthe invention will become apparent from the following description taken in connection with the accompanying drawing in which:

Fig. 1 is a bottom view of the cushion insole member embodied in the improved sh'oe construction:

Fig. 2 is a top view slightly in perspective of the cushion insole member with adhesive applied thereto;

' Application May 19, 1944, Serial No. 536,257

( Cl. Sti-19.5 )v s shoe, said view being taken on the line I4-I4 oi' Fig. 13.

Referring to the drawing in detail, and first to Figs. 1 to 3, I indicates an insole member which is preferably made of a yieldable material, such as cork, rubber, or the like, in order that the shoe may be given a cushion upon which' the foot Fig. 3 is aview of the cushion insole member with the sock lining attached thereto;

Fig. 4 is a view of the tab which is employed to cover the toe end of the insole member of the shoe;

Fig. 7 is a view of the parts shown in Figs. 3, 4, 5 and 6 after being sewed together;

Figs. 8, 9 and 10 are sectional views showing details of construction, said views being taken on the lines 8 8, 9 9 and I0-I0, respectively, of Fig. 7;

Fig, 11 is a bottom view of the shoe showing its construction prior to the application of the out- Fig. 14 is a sectional view ofthe completed of the wearer can rest. This insole member I has adhered to one side, by a suitable adhesive, a. piece of fabric 2 which is relatively nonstretchable in order to give support to the member and prevent its spreading in a lateral direction. This fabric member is preferably on the bottom side of said member, which side is shown in Fig. 1. The top side of the insole member I is shown in Fig. 2, and this side is given a coat of adhesive material so that it can have secured thereto a sheet or sock lining 3 of the shoe. This sock lining may be made of any suitable material, such as fabric, leather, or the like. 'Ihe sock lining, if made of fabric, may comprise two sheets of material adhered together preferably with the upper sheet of a color and texture to blend with the shoe upper and present a. pleasing appearance.v The sock lining is cut to be of slightly larger size than the insole in order to provide an extending marginal portion 4, as best seen in Fig. 3.

As shown in Fig. 5 the upper 5 of the shoe comprises an outer part 6 and an inner part or lining l. These two parts are died out of any suit able material, and the upper marginal edges secured together by stitching 8. The upper shown is for anIopen-heel type of shoe which mayhave a heel strap extension 9 and a buckle I0 to provide for adjustment. The upper shown is also formed to provide an open toe and the outer part of the upper and the lining are secured together by stitching I I at the toe end. The size of the upper, particularly the lining as cut out by the die, will determine the size of the shoe. The outer part of the upper is cut so as to be larger than the lining part in order that the lower marginal portions I2 of the upper may extend beyond the lower marginal edges I3 of the lining. It is to be particularly noted that the lower marginal portions of both the outer part and the lining part of the upper are in unsecured relation to eachother.

The upper of the shoe, after having been sewed together in the manner shown in Fig. 5, is next attached to the sock lining which as previously described has secured to it the cushion insole member. The attaching of the upper to the sock lining is preferably performed by stitching I4.

In addition to the upper being stitched to the sock lining is also employed to secure the tab Il and the strip Il to this member. 'I'h'e upper, the tab and the strip are all attached to the extending or marginal portion l of the sock lining which as noted projects beyond the edge of the insole. In attaching the upper l to the sock lining, only the marginal portion of the lining 1 of the upper adjacent to the edges i3 is stitched to the marginal edge or the extending part of the sock lining. The heel strip Il is of such length that when attached to the sock lining it will overlap the rear ends of the lower marginal portion of the upper lining part 1 and extend beneath the rear ends of the lower marginal portion of the outer part of the upper, as shown in Fig. 7. -The toe tab 4Il is also of such' length that whensewed to the insole it will overlapthe toe ends of the lining part 'L After the upper, the toe tab and the heel strip are sewed to the sock lining, the resulting construction will be that shown in detail in Figs. 7, 8, 9 and 10. this construction also having the insole 2 since it and the sock lining were secured together prior to the attachment of the upper, the toe tab and the heel strip. Into the stitched together sock lining and upper is inserted a suitable last il shown in Fig. 12. With the last in place the outer marginal portion of the fabric on the bottom side of the insole is given a coating of adhesive preparatory to pulling over the lower marginal portion of the outer of the upper, the toe tab and the heel strip. However, before this is done, the shank piece il is associated with the bottom side of the insole together with a shank brace Il of' suitable nbre or other material in order to present a proper arch construction for the shoe, together with a firm and rigid heel seat. The toe tab and the heel piece are first pulled over their connecting seams and adhered to the bottom of the insole, thus providing an encasing or cover strip for the toe and heel edges of the insole. Next the lower marginal portions I! of the outer part of the upper are pulled down and over the edges of the insole and adhered to the bottom surface of the same. In pulling over the lower marginal portions of the upper. the seam produced by the stitches Il in connecting the marginal edges of the lining and the sock lining is forced into a vertical position, as shown in Fig. 14, and firmly confined between the edge of the insole and the outer part of the upper, thus making a compact construction at the edge of the insole.

The shoe is now complete with the exception of the attachment of the outsole and the heel. These two parts are attached in the usual manner. The outsole 2l is preferably cemented to the bottom of the insole and to the surface of the lower marginal portions of the upper, which are secured to the bottom of the insole. 'Ihe outsole is attached while the last is in the shoe, and this may be accomplished with the usual lasting machine which ilnnly holds the outsole against the insole during drying of the cement. The heel 2 i may be attached in any suitable man- V ner, such as by a screw which extends through glued to the heel portion of the sock lining. If desired. this piececan also be sewed to the sock lining, the sewing being done before the sock lining and insole are secured together to form the construction shown in Figure 3.

From the foregoing description, it is seen that the improved shoe is constructed by means of very simple operations. yet the shoe when ilnished is sturdy, while at the same time being very ilexvfoot of the wearer will have the same degree of cushioning. Thus there is no possibility ot the foot being supported by yieldable material at its' center and by more rigid material at its edges as would be the case in constructions where -a yieldable piece of material is inserted in a cut out part of an insole. It is to be noted further that with the particular construction shown the yieldable insole also extends beneath the heel of the wearer, thus giving a complete cushion support for parts of the foot of the wearer which rest upon any part of the shoe.
